Talk to me about dual mass flywheels.

65k on clock and 55 plate. Banging on from engine bay when clutch is pressed and depressed. Thought intilally it was a belt as it only happened when cold but that was a red herring as when getting going I didn't drive with clutch in for a period of time.

If you get a new clutch fitted make sure you get your mechanic to make sure the starter motor hasn't swallowed a load of bits.
My car(mondeo) had the starter motor replaced when it happened and its been removed for cleaning 3 times since.

valeo do dual mass conversion kits for most motors now you can convert it to a standard clutch which will last donkeys but i am not sure how it will change the characteristics of the clutch i believe it makes it heavier and possibly more vibration. my van will be getting done when the clutch goes as £800 for a clutch change is a joke.

Mmm, our zafira 04 diesel just ad the same problem. Not going into gear, but only sometimes. Got worse over time and then got the knocking noise. Just parts include vat for dmf and clutch are about 550 ish ( trade ), dealer quoted about 1600 to fix it! 8O. Brother in law did it for price of the parts, about a a labour.

And yes, get starter motor checked, magnet in there will collect all shattered bits of dmf I have been told.

The dual mass flywheel is there to smooth out the pulses of torque from a diesel at low revs, replacing it with a single mass conversion kit will result in more vibration. Can't be that bad though, my works transit (and thousands of others on the company fleet) had its dual mass flywheel swapped out to a single mass as soon as it left the factory to prevent later breakdowns, and it doesn't seem to have adversely affected it much.

hi dont know if this helps i had a 2006 06 vectra 1.8 vvti 140bhp. it always juddered and the cause was down to vauxhall fitting sub standard parts , i believe the organic materials they use were not up to the job. this was a hush recall in the vectra and you had to know about it to ask to get it done, i also belive it was common on astras too. might be worth a search on vauxhall forums to see if it was a problem with your car , i was told the flywheel clutch and fitting would have been around 1600(main dealer)
